Analysis of Influencing Factors of Magnetic Flux Leakage Testing Metal Tank Bottom Based on Finite Element Method

摘要

In this paper, the magnetic flux leakage testing equipment of military metal oil tank is taken as the research object, and a finite element model is established by numerical simulation. The impact of the defect depth, liftoff value and plate curvature on magnetic flux leakage was calculated. The results of this study can guide the safe operation of military oil tank inspection technology, in order to ensure the quality of military oil to provide support, with greater military and economic benefits.
